Electronic doping of graphene by deposited transition metal atoms
Jaime E. Santos, Nuno M. R. Peres, Joao M. B. Lopes dos Santos +1
We perform a phenomenological analysis of the problem of the electronic doping of a graphene sheet by deposited transition metal atoms, which aggregate in clusters. The sample is p…
Metallic Continuum Quantum Ferromagnets at Finite Temperature
Antonio H. Castro Neto, Marcello B. Silva Neto
We study via renormalization group (RG) and large N methods the problem of continuum SU(N) quantum Heisenberg ferromagnets (QHF) coupled to gapless electrons. We establish the phas…
P-wave pairing and ferromagnetism in the metal-insulator transition in two dimensions
Claudio Chamon, Eduardo R. Mucciolo, Antonio H. Castro Neto
Based on recent experimental evidence for a spin polarized ground state in the insulating phase of the two-dimensional electron system, we propose that ferromagnetic spin fluctuati…
Non-Fermi Liquid Behavior in U and Ce Alloys: Criticality, Disorder, Dissipation, and Griffiths-McCoy singularities
Antonio H. Castro Neto, Barbara A. Jones
In this paper we provide the theoretical basis for the problem of Griffiths-McCoy singularities close to the quantum critical point for magnetic ordering in U and Ce intermetallics…
